The official decision will not come until next year, but the international technology concern did not want to wait that long before revealing its achievement. On the occasion of the ceremony to celebrate the 50 millionth Ceran glass-ceramic cooktop in Mainz on April 17, 2002 Frank Buchholz, the well-known chef from the VOX-Kochduell (VOX Dueling Chefs) television program, cooked for the guests on the record piece of glass-ceramic.
To manufacture this unique item called for a high degree of precision. As it was no thicker than a normal panel, which is only 4 mm, the record-sized cooktop was as flexible as a sheet of paper. If, by way of comparison, the cooktop were shrunk to the standard size it would only be 0.3 mm thick.
One particular challenge that the record cooker presented was the enormous amount of power it required which, at about 65 kW, was roughly the amounted needed by a detached house. A special power line had to be installed for it about 100 meters long.
Whether the giant cooktop makes it into the Guinness Book of Records or not it is in any case incontrovertible proof of the creativity that continues to flourish without letup at Schott in the generation of innovations. And that is just one of the main reasons for the product success of Ceran millions of times over.
